Answer:
it is an undefined slope meaning it has no slope or change so there is no equation
Step-by-step explanation:
I have taken a class on this but if it only goes straight up and down it is undefined
First 10 days...average daily increase of 0.30 .....total increase for those 10 days is (0.30 x 10) = $ 3
next days.....average daily increase of 0.45....total is (0.45 x 10) = 4.50
last ten days...average daily increase of 0.25.....total is (0.25 x 10) = 2.50
it changed all together : 3 + 4.5 + 2.5 = + 10
It is showing an overall increase, so I guess u should buy it.
Answer:
828
Step-by-step explanation:
Missing leg of triangle:
√15²-12²= √225-144=√81=9
Triangle faces= 2*1/2*12*9= 108
Base= 20*9= 180
Front face= 20*15= 300
Back face= 20*12= 240
Total= 108+180+300+240= 828
Second choice
If you take the derivative of your equation, you get:
2′″−″−′+′=0
2
y
′
y
″
−
x
y
″
−
y

+
y
′
=
0
or
″(2′−)=0.
y
″
(
2
y

−
x
)
=
0.
Let =′
v
=
y
′
and we have ′(2−)=0,
v
′
(
2
v
−
x
)
=
0
,
so either ′=0
v
′
=
0
and =
v
=
c
or =/2
v
=
x
/
2
.
Then ′=
y
′
=
c
and so =+
y
=
c
x
+
d
or ′=/2
y
′
=
x
/
2
and =2/4.
y
=
x

/

Plugging the first into the original equation gives =−2
d
=

c

. So there are two solutions =−2
y

x
−
c

for some constant
c
and =2/4
y

/

. I don't know if this is all the solutions
